1 The base of a solid is a circular disk with radius r. Parallel cross-section perpendicular to the base are triangles with height h and unequal side in the base.A, Set up an integral for the volume of such a solid.B, By interpreting the integral as an area, find the volume of thi...
B right circular cone 那种正圆锥,从圆锥顶点到地面圆心的那条线就是高,这条高跟圆锥底面垂直. 现在这个圆锥在半球中内接,也就是说,圆锥的顶点在半球的表面.而且告知圆锥地面跟半球底面重合,所以两个圆心重合.所以圆锥的高其实就是从半球的圆心到半球表面之间的距离,那个不就是半球的半径么? 所以就是1:1结果...
